FNB CRS Department a NIGHTMARE and no FEEDBACK. Threatened with account FREEZE

I laid a complaint in the week about the connect department. Turns out it is an ISSUE within the very RUDE CRS department, who basically threatened to Freeze my account if I don't send in a Self Certification form through (tax number etc.) I have sent and requested confirmation that they've received the document and that that is sufficient. I was told that I can't apply for ANYTHING until this is sorted out. NEVER KNEW THERE WAS AN ISSUE TO BEGIN WITH! I need the CRS department to contact me so we can resolve what ever issue they might have in regards to missing docs. They REFUSE to get back to me by phone or email. This is causing problems and STRESS as I don't know whether my account will be frozen due to a document that NO ONE AT FNB EVER INFORMED ME I NEEDED TO COMPLETE TO STAY COMPLIANT WITH THEIR NEW LAW now over the damn HOLIDAY PERIOD! No communication from the CRS (Common Reporting Standard) Department at FNB to get ANY FEEDBACK. But what can you expect when the call basically started back to begin with. I need this to be ADDRESSED, so that we can see if more documents are needed or if it's sufficient and to PUT MY MIND AT EASE about my accounts not being frozen over the holidays for NO REASON.
